PURPOSE:To make this device compact by integrating water separators on the intake side and the discharge side of a water-sealed pump, arranging it on the water-sealed pump, and driving the drainage pump of the intake side separator and the water-sealed pump with a common rotary shaft. CONSTITUTION:Water separators 12, 13 on the intake side and the discharge side of a water-sealed pump are integrated into a box shape and arranged on the water-sealed pump 11. The drainage pump 14 of the intake side separator 12 if fitted to the end face section of the water-sealed pump 11, and they are driven by a common rotary shaft 11d. Accordingly, the water-sealed pump, water separators, and the drainage pump can be arranged cubically, and the whole device can be made compact.
